This invention relates tonew and useful ilnprovernen'ts in machinesdesigned for the purpose of exterminatin'g boll Weevilsand' other!destructive insects,' and it rcfers par-f ticularly to a; machine oftheiclassdesignatecLWespecially equipped with facilities for carrying.more than a single rowyasin the case of its applicability toWeevilirifested cotton; :3

The invention primarily' ooinpreherids' the "PIOVlSlOIlYOf a fan,.arrangedthrough sue tion, to remove insects and other infectedparticlesxfrom the plants as the machineis 7 viewof the fan in axialcrosssect1on,hke-

, In proceeding further ini detail, new, isdirected to the drawings,wherein the ma; chine is shown provided with wheels 1 ro-vv tatablymounted upon the axles QQW hl Ch latter are adjust-ably afiixed to theframe 3, upon Which aneng'ine 4 is mounted and securely held in. placeby straps 5 in such a manner as to swing the greater portion of theweight'of the englne below the center- "levelof theaxles 2. I k The fan6 is situated directly 'above the engine 4 uponv the frame 3 and securedin position by means of straps 7, While the fly Wheel or propellingpulley 8 is disposed be- "neath the fan, slightly rearwardly thereof.

Uponthe fan shaft 10 is situated a fan pulley 9, the former beingmounted in ball bearings 11, which areisecured upon one of thestraps 7and an outerstrap or brace 12 which latter'has its lower ends affixed totherearends of the frame f a 1.3'upo'n thepulleys 8 and 9, an idlerpulley l6'is provided as in Figure 3 of the draw mgs, which is situatedupon a spindle 17,

the latter being bentinto suitable shape so as to extend downwardly and'along the frame ,3, to which it is fastenedby straps (notshown) I anditslopposite end bent upwardly, acting'asa lever arm 19,'Whereby toactuatesaididler pulley 16 out of contaot with the belt 13, as the saidpulley is held] against the belt by a tension spring so i 20, a view ofwhichisillustrated only in" i -r *rFigure13. F gure 1 represents a frontelevational view offthe-inventmn, illustrating aismgle A lateral suctionpipe 21 is provided, Which preferablyY'Tshaped in form there- 'tobranch; out to each row andr'upon either end is secured flexibleconduits22 and adapted to depend therefrom; Upon the ends of the conduits 22,cones 23 are aiiixed as illustrated in Figure 1," which latter conformswith the rowe of vegetation on either slde thereoi. This arrangementpermlts plants tolpas's directly beneath. the suction line, andbywvhichall infected I or fallen v squares as ivell as other particlesiniestedwith weevils and other insects areigathered and carried through thesuction'line 22 and intocontact with. the fan blades, 2 L, (seelFig-uresfi and6) which latter are mounted upon a spider 25, The backside'oi the fan "blades 2 liare secured to a cone shaped disc 26,.andthe blades are flared at their ends so as to produce an uneven pressureat the outer points thereof, thus forcing the squares and otherinfestedparticles to dip back into the blades, as indicated by thearrows in each of the Figures 5 and '6, thus thoroughly pulverizing theyoung bolls and squares, to destroy all eggs and larvae of the insects,as well as theinsects themselves.

It should be further observed that the fan is of such construction thatthe eddy currents of air indicated by the broken lines and arrows, carrythe masses of 'matter drawn thereby about therblades .a number of timesat a high rate of speed inorder to thoroughly beat them to pieces andexpel the same through the discharge line 27 which latter isbifurcatedas shown in Fig-v ure-3, the purpose-of which will be later made clear.V

The cones 23, it will be observed, are controlled through theactuationof a lever arm 28, which latter has its rear end pivotedto I abracketr29, (see Figure 3) andiwhich is secured to the axle 2. A'chain30 is secured to the front end of the lever 28, while the opposite endthereof is secured to a'lifting lever 31, which is affixed to a rod 32mounted 7 upon the under side of the tongues 33 by. bra'ces34, as inFigure i. A hand lever 35 V is afiixed to the said rod 32 and a notchedbracket 36 is secured upon a cross-brace 37 and 38 and is fitted withthe. said hand lever 35, whereby whenthe dog 39 is lifted by depressingthe hand grip 40, by way of pulling the connecting link 41, the lever ispulled back or adjusted to the place desired and held by spring L2. Thisarrangement regulates the position of the cones 23 to a posi tion abovethe plants.

A seat 43 is further provided which is secured on the top side of the Ushaped strap 44, which in turn is afiixed to the frame 3.

Attention is again directed to the tongues 33,'two of which areprovided, which'are supported by as many cross-bars 37 and 38. The twosaid bars are afiixed to the front of the frame 3 and under the bar 37 adouble.

tree 45 is pivoted centrally thereof and to each end of the same, singletrees'fidare fastened in the usual manner, whereby to permit the horses,or other propelling agent to travel between the rows. 3

The usual engine radiator 47 is shown,

3 which is secured to the frame 3, preferably under the seat 43, asshown. 7

It will be observed in Figure 2 that a double suction 48 is provided,which affords an independent suction for either side of the row andpermits the plants to pass between same. The, [suction e picks up allfallen squares from the middle, as wellas'from under'the stalks andmaybe employed for use on cotton that" has reached thematured stage. Theauction arrangement employedupon the machine i ustrated Figu e 1,whereonthe cones 23 are used is'more especially adapted for cottonin theearly stage of growth, however, it should be understood that theseclifferent arrangements may be interchangeable,

' depending upon the size of the plants upon which it is desired to beused.

" It has been found desirable when working a row of plants, to agitatean adjoining row prior to working, in order to shake off all looseandinfected squares, as well as weevils, which are known to sull anddrop oif when molested. A novel arrangement has been.

devised, which'consists of the bifurcated end on the discharge pipe 27,as previously men tioned. Air pressureinduced'by the fan 6 being'passedthrough this pipe as well as particles of pulverized matter, permits thesame to be readily used, when directed towardan adjoining row ofunworked plants, 7

to shape the stalks for the purposes mentioned, and a small trap door 49is employed to direct the current of air through'either of the ends ofthe pipe 27 desired. 5 See Figure 3. y

It should be understood herein that it is not desired that theinventionbe limited to the specific'disclosure herein set forth,and thatcertain minor changes and modifications may be resorted to as fallwithin the meaning and'scope of what I claim: 1 V r 1; In" an insectexterminating mach1ne,the
